Quality management in clinical microbiology began in the 1960s. Both government and professional societies introduced programs for proficiency testing and laboratory inspection and accreditation. Many laboratory scientists and pathologists were independently active and creative in expanding efforts to monitor and improve practices. The initial emphasis was placed on intralaboratory process. Later, attention was shifted to physician ordering, specimen collection, reporting, and use of information. Quality management in the laboratory depends in large part on the monitoring of indicators that provide some evidence of how laboratory resources are being used and how the information benefits patient care. Continuous quality improvement should be introduced. This consists of a more thorough assessment of doing the right things versus the wrong things in terms of customer demand and satisfaction and studying the cumulative effect of error when responsibility is passed from one person to another. Prevention of error is accomplished more through effective training and continuing education than through surveillance. Also, this system will force more conscious attention to meeting the expectations of the many customers that must be satisfied by laboratory services, including patients, physicians, third-party payers, and managed-care organizations.

An internal quality assessment scheme (IQAS) can be used to monitor the quality of work more frequently and reproduce normal test conditions more accurately that NEQAS. IQAS samples can be provided in sufficient numbers and should not be more vigorously tested that any other routine specimen.In the IQAS some specimens received in the laboratory are resubmitted for testing anonymously, thus all activities involved in the passage of specimens through the laboratory starting from reception and ending in the dispatch of final report can be monitored.8 The samples chosen can realistically reflect the diversity of tests in current use, and the numbers can be sufficiently high to monitor all laboratory procedures with precision but without increasing the workload excessively.Here, we report on the organisation and performance ofan IQAS used in the diagnostic virology laboratory of the Clinical Microbiology and Public Heath Laboratory, Cambridge, since April 1991 to assess the performance of the serology section. For organisational reasons, antibodies against other microbiological agents (Chlamydia sp, Coxiella burnetii, Mycoplasma pneumoniae, Legionella pneumophilia, Toxoplasma gondii) were also tested in this section. A total of 715 anonymous serum samples (IQAS) to test 3245 individual procedures

Laboratory identification and sensitivity testing of yeast isolates

Methods used for identification and sensitivity testing of yeasts are presented. Identification depends on both morphologic features and biochemical characteristics. The germ tube test is a simple test for the identification of the commonest yeast pathogen, Candida albicans. Species not identified by this method can be identified by means of several other tests, the most important being the carbohydrate assimilation test. Several kits are commercially available and most appear to be satisfactory. Antifungal susceptibility tests are not standardized, and results are often subject to considerable variation. Until improved methods are developed, it might be advisable that smaller laboratories only do a preliminary screening test for flucytosine susceptibility and, if indicated, also for amphotericin B susceptibility. Important isolates should be sent to laboratories with a special interest in antifungal susceptibility testing for more extensive testing.
